Patent ES-8206093-A1 (ES)
Title: Light and particle image intensifier.
IPC: H01J31/50
Filed: 1981-07-28
Abstract: A light and charged particle image intensifier receives incident image conveying light or charged particles ("incident beam") and provides to data processing and video equipment signals from which the image conveyed by the incident beam can be constructed and displayed. The beam that is being processed includes visible light reflected from objects and X-ray radiation that has been passed through an object such as a human body. The image intensifier includes a scintillator and photocathode unit for converting the incident beam to photoelectrons and a charge-coupled device ("CCD") for detecting the photoelectrons and transmitting to the data processing and video equipment information relating to the quantity or energy level as well as the location of the electrons impinging on the sensing areas of the CCD. From this information, the data processing and video equipment can reconstruct the image conveyed by the incident beam. The sensitivity of the device is increased either by imposing an electric field across the photocathode and the CCD to accelerate the photoelectrons or by placing a micro channel plate ("MCP") between the photocathode and the CCD to increase the number of electrons that impinge on the CCD. Alternately, a silicon diode target can be used instead of a CCD to intercept the electrons and an electron beam gun can be used to detect the location and intensity of the charges created on the target by the impinging electrons. Finally, a grid having a number of windows can be used instead of a CCD or a silicon target to detect the location of the electron streams and a photoanode can detect their intensity.

Title: Method of constructing a concrete off-shore structure more than 200 m high stabilized on the sea bed by its own weight
IPC: E02B17/02
Filed: 1981-10-20
Abstract: The structure is made in several "storeys" (D1, D2, D3). These are floated away from their construction site in conventional manner. Once in sufficiently deep water, the storeys are tilted over so that they float on their side, and they are then joined together end-to-end. With tilting and rotating operations performed by suitable ballasting and unballasting of compartments in the storeys, the joining operations can all be performed on members at or near (just above or just below) the surface of the water. Once the storeys are assembled together, the entire structure may be towed on its side to a point of use, and then immersed so that it stands vertically on the sea bed.

Patent ES-8401917-A1 (ES)
Title: Multiple orifice bushing.
IPC: C03B37/02
Filed: 1982-09-13
Abstract: A process for manufacturing glass filaments in which the bushing bottom plate has tips depending therefrom and each tip has a plurality of orifices from which glass filaments are drawn. The tips flood individually on start-up or during operation, and the flood results in a single composite filament being formed from the orifices of that tip. The composite filament beads down rapidly and is subsequently separated into individual filaments by the use of a fluid spray directed against the composite filament at the tip lower face. The fluid spray is utilized to momentarily quench the composite filament and is terminated once separation occurs. Subsequent filament drawing is accomplished without the use of a cooling fluid and by the use of known heat exchange means, e.g., a flow of cooling gas.

Patent ES-8406219-A1 (ES)
Title: Apparatus for the pelletization of heat-liquifiable solid materials
IPC: B22F9/10
Filed: 1983-05-03
Abstract: Apparatus for the pelletization of heat liquifiable materials, such as metallurgical slags consists of a downwardly-extending feed plate onto which the molten material is fed together with water, if required to promote the expansion of the molten material and for control of the cooling. The material discharges from the feed plate onto a rotating radially vaned drum by rotor by which it is projected into the air for simultaneous cooling and pelletization after it has first passed through a flow control gap formed between the feed plate surface and the periphery of a second rotor mounted above the feed plate. The second rotor is rotated in the direction such that it promotes the flow of the molten material down the plate, forcing the material between the vanes of the projecting rotor, while at the same time spreading the material across the width of the plate against its natural tendency to form a compact stream. The flow of the material is thereby made more uniform, providing for more effective use of the projecting rotor and avoiding localized flooding of the vanes with consequent loss of pelletization. The resulting apparatus can also be more compact for a given output. In some circumstances the second rotor can with advantage be rotated against the direction of flow down the feed plate.

Patent ES-8608113-A1 (ES)
Title: Lance for accelerating solid particles.
IPC: C21C5/46
Filed: 1985-05-14
Abstract: An acceleration nozzle for particles entrained in a carrier gas comprises a first central nozzle having a first diverging cross-section, and an extension nozzle section extending from the first nozzle. The extension nozzle section has a flare or diverging angle which is greater than that of the first acceleration nozzle. The nozzle extension is surrounded about its mouth or opening by a second nozzle forming a casing or housing therearound the second nozzle being connected to a source of gas. In a preferred embodiment, instead of utilizing two distinct gas sources to supply the first acceleration nozzle and the second "housing" nozzle, a portion of the gas passing through the acceleration nozzle may be diverted by means of slits built into the latter. The slits act as a separator of the gaseous phases and solid particles, and prevent the solid particles from penetrating the second nozzle. Acceleration nozzles of the present invention are typically used for delivering carboniferous powdered materials into a steel bath.

Patent ES-8609593-A1 (ES)
Title: Controlling glow plugs in an internal combustion engine
IPC: F02P19/02
Filed: 1985-07-02
Abstract: When a switch S is closed, a comparator 2 causes an astable multivibrator 4 to close a switch 8 thereby supplying power to glow plugs A and lighting a lamp 2. Eventually the voltage across a capacitor C2 equals a reference voltage UREF2 whereupon the comparator 2 causes the multivibrator 4 to switch off the power supply to the glow plugs and also turns off the lamp 2. The engine is ready to be started. When there is no current supply to the glow plugs, they act as thermocouples whose voltage is compared in a comparator 1 with a reference voltage UREF1 to keep the glow plug temperature at that necessary for igniting fuel. An engine temperature probe R5 connected to a comparator 3 turns off the power supply to the glow plugs when the voltage across a capacitor C3 equals a reference voltage UREF3.
